The above nutrient is, for example, a nutrient which is mainly composed of nitrogen or phosphorus and contains a trace amount of potassium magnesium or calcium and is essential for the activation of microorganisms. In the above-described micro-nano bubble generator 23, an air suction pipe is connected to: a valve 24 for adjusting the air intake amount is connected to the Sib 25; and the above-mentioned micro-nano gas 121117.doc is connected to the bubble generator 23. 1359116 The water in the tank 1 is supplied to the production pump 26 in the above-described micronized bubble generator 23. Further, the micronized bubble generator 23 supplies water from the circulation pump %, and takes in air from the air suction pipe 25, and the water and the air generate a vortex flow at an excessive speed, and finally after a fixed time. Generate micro-nano bubbles. The circulation pump 26 supplies water to the micro-nano bubble generating machine 23 in a desired pressure state. When the supply is performed under the required pressure state, micro-nano bubbles can be efficiently generated. The so-called required pressure means a pressure of 15 kg/cm2 or more. As the above-described micro-nano bubble generator 23, if it is a commercially available product, there is no need to limit the manufacturer, specifically, the Nan〇planet Institute Co., Ltd. or

Goods of Aura-tec AG or Nomura Electronics Industry Co., Ltd. Other commodities, such as the microbubble water manufacturing device of Xihua Industrial Co., Ltd. or the microbubble water manufacturing device of the Resources Development Co., Ltd., may be selected according to the purpose. Here, the above-mentioned micro-nano bubble refers to a bubble having a diameter of ΙΟμιη to several hundreds nm & right. In addition, the usual bubbles (bubbles) rise in the water and rise and break when they reach the surface. Further, the term "microbubble" means a bubble having a bubble diameter of 1 〇 um to several tens μίη, which shrinks in water and eventually disappears (completely dissolves). Further, the term "nano bubble" means a bubble having a diameter of several hundred nm or less and is always present in water. Moreover, the micronized bubbles can be understood as bubbles mixed with microbubbles and nanobubbles. Further, in the above-described micro-nano bubble generating cell, by adding the above-described micron-forming bubble generating auxiliary agent, the above-mentioned micro-nano bubble generating machine 23 can produce 121117.doc 1359116 into the optimal micro-nano bubble. . The water stream 27 is generated by the fine bubbles ejected from the micro-nano bubble generator 23, and the water stream 27 becomes the circulating water flow of the micro-nano bubble generating tank 1 and is then subjected to the inside of the micro-nano bubble generating tank 1 Stir.

When the microorganisms in the above activated carbon are not propagated, the ability of the activated carbon to adsorb the organic substances is lowered after the water is continuously introduced into the activated carbon. However, if the activity of the microorganisms propagated in the above activated carbon is strong, the organic matter adsorbed by the activated carbon is decomposed to a state in which the activated carbon is regenerated. 121117.doc •20- 1359116 Previously, in the associated waterworks of the water supply pipeline, the activated carbon was regenerated by microorganisms due to the low organic matter flowing into the water, but under the condition of drainage, the organic load was relatively high. High, resulting in the above-mentioned activated carbon is difficult to regenerate. Therefore, in the present invention, if microbes are used to activate microorganisms in the water to be treated, and microorganisms are propagated in the activated carbon as an immobilization carrier, even if organic matter is present in the drainage,

The so-called bioactive carbon which is an eight-strong automatic regeneration capability does not require the activation of the activated carbon in the activated carbon column 4, thereby reducing maintenance costs and operating costs.

The bubble is thereby made into a washing water.

After the tank 9, the tank 9 is treated by the above-mentioned washing water. The exhaust treatment tank 9 includes a water spray unit 10 disposed at an upper portion of the upper portion. The lower water storage unit 11 houses the lower water storage unit 11 and the micro-nano bubble generator 121117.doc -23- 1359116 12, and stores the washing water. The upper water spray portion ι depends on the washing water extracted from the lower water storage portion 11. The exhaust water passing through the upper water spray unit 1G·w is exhausted and stored in the lower water storage unit Μ, so that it can be sucked into the upper water spray unit 1 by spraying the fruit 17 again. The upper water spray unit 10 includes a perforated plate 18, a plastic filler 19 (for example, a product name 亍, u^b), and a water spout 20 in the order from the top, in the upper water spray unit 10, An exhaust outlet 22 is provided at an upper portion of the water spout 2 . Further, the fluorine-containing exhaust gas flows from the duct 7 provided between the upper water spray unit 1A and the lower water storage unit η to the exhaust gas treatment tank 9, and is sprayed by the water spray nozzle 20. After the washing water is sprinkled, it is discharged from the exhaust outlet 22. The micro-nano bubble generator 12 is housed in the lower water storage unit 11. The above-described micro-nano bubble generator 12 has the same configuration as that of the above-described micro-nano bubble generator 23, and therefore its description will be omitted.

When the field is formed into an evaporating or easily vaporized organic fluorine compound, it is absorbed by the washing water and then decomposed by the microorganism activated by the micronized bubbles in the lower water storing portion u. Then, the washing water in the exhaust treatment tank 9 is continuously reduced from the start of the operation/evaporation or scattering from the exhaust outlet 22, and the reason is that the makeup water is automatically replenished (not shown). The ball hydrant can automatically replenish the hydration 'to make the liquid level of the lower water storage part 11 121117.doc
